Can my septum become loose from scratching inside my nose?

Hey doctors. I keep overthinking a lot and this has been stressing me out and giving me a lot of anxiety. I know that I only have an L strut left and am just concerned how well connected it is without becoming loose. If it is so easy to harvest cartilage maybe it can become loose easily especially because there in only a very small amount at the caudal area. Sometimes I have to itch my nose inside with my finer gently and am nervous the septum will become loose...It really concerns me?
